Definitions
- Glaucoma is a degenerative disease of the eye wherein the intraocular pressure is too high to permit normal eye function. As a result, damage may occur to the optic nerve head and result in irreversible loss of visual function. If untreated, glaucoma may eventually lead to blindness. Ocular hypertension, i.e., the condition of elevated intraocular pressure without optic nerve head damage or characteristic glaucomatous visual field defects, is now believed by the majority of ophthalmologists to represent merely the earliest phase in the onset of glaucoma.
- pilocarpine and ⁇ -adrenergic antagonists reduce intraocular pressure
- none of these drugs manifests its action by inhibiting the enzyme carbonic anhydrase, and thus they do not take advantage of reducing the contribution to aqueous humor formation made by the carbonic anhydrase pathway.
- carbonic anhydrase decrease the formation of aqueous humor by inhibiting the enzyme carbonic anhydrase. While such carbonic anhydrase inhibitors are now used to treat intraocular pressure by systemic routes, they thereby have the distinct disadvantage of inhibiting carbonic anhydrase throughout the entire body. Such a gross disruption of a basic enzyme system is justified only during an acute attack of alarmingly elevated intraocular pressure, or when no other agent is effective.
- Prostaglandins are members of a class of organic carboxylic acids that are contained in human and most other mammalian tissues or organs and that exhibit a wide range of physiological activities. Naturally occurring Pgs possess a common structural feature, the prostanoic acid skelton, depicted in Formula I below:
- the primary PG's are classified based on the structural feature of the five-membered cycle moiety into PGA's, PGB's, PGC's, PGD's PGE's, PGF's PGG's PGH's PGFs and PGJ's and also on the presence or absence of unsaturation and oxidation in the chain moiety as: Subscript 1 13,14-unsaturated-15-OH, Subscript 2 5,6- and 13,14-diunsaturated -15-OH, Subscript 3 5,6-13,14-, and 17,18-triunsaturated- 15-OH
- PGFs are subclassified as or ⁇ according to the configuration of the hydroxy group at position 9.
- Prostaglandins and prostaglandin derivatives are known to lower intraocular pressure.
- U.S. Patent 4,824,857 to Goh et al. describes the use and synthesis of PGD2 and derivatives thereof in lowering intraocular pressure including derivatives wherein C-10 is replaced with nitrogen.
- U.S. Patent 5,001,153 to Ueno et al. describes the use and synthesis of 13,14-dihydro-15-keto prostaglandins and prostaglandin derivatives to lower intraocular pressure.
- U.S. Patent 4,599,353 describes the use of eicosanoids and eicosanoid derivatives including prostaglandins and prostaglandin inhibitors in lowering intraocular pressure.
- Prostaglandin and prostaglandin derivatives lower intraocular pressure by increasing uveoscleral outflow. This is true for both the F type and A type of Pgs and hence presumably also for the B,C,D,E and J types of prostaglandins and derivatives thereof.
- a problem with using prostaglandin derivatives to lower intraocular pressure is that these compounds often induce an initial increase in intraocular pressure.
- the combination of the carbonic anhydrase inhibitor and the prostaglandin derivative can be used for the treatment of diseases and conditions in which the lowering of intraocular pressure is desired, for example glaucoma, ocular hypertension and other disease accompanied by an increase in intraocular pressure.
- the activity of the carbonic anhydrase inhibitor currently marketed wanes 6 to 8 hours post-dose, meaning that as single agents these carbonic anhydrase inhibitors must be administered at least three times day to maintain the desired lowering of intraocular pressure.
- the combination of this invention maintains the desired lowering of intraocular pessure for a full twelve hours. Because of this increased duration of action, the combination disclosed herein is effective when administered only twice a day. Patient compliance is anticipated to be greater with twice a day administration than with three times a day administration.
- the combinations disclosed herein are effective either by co-administration of the medicaments in one solution or as a combined therapy achieved by prior administration of either the carbonic anhydrase inhibitor or the prostaglandin derivative followed by administration of the other solution.
- the use of a single solution containing both active medicaments is preferred.
- This invention relates to novel ophthalmic compositions comprising a topical carbonic anhydrase inhibitor or an ophthamologically acceptable salt thereof and a prostaglandin or prostaglandin derivative thereof or a hypotensive lipid derived from a prostaglandin or prostaglandin derivative such as a PGF2 prostaglandin.
- composition comprising 0.025 to 5% (w/w) of a topical carbonic anhydrase inhibitor such as 5,6- dihy dro-4-ethy lamino-6-methy l-4H-thieno- [2,3 -b] thiopyran-2- sulfonamide-7,7 dioxide hydrochloride or 2H-thieno[3,2-e]-l,2-thiazine- 6-sulfonamide-4-(ethylamino)-3,4-dihydro-2-(3-methoxypropyl)-l,l- dioxide and their trans and cis enantiomers, or an ophthalmologically acceptable salt thereof, including racemic material and 0.005 to 2% a hypotensive lipid derived from prostaglandins and their trans and cis enantiomers, or an ophthalmologically acceptable salt thereof, including racemic material is disclosed.

- PGF 2 ⁇ prostaglandin is derived from PGF 2 ⁇ prostaglandins, in which the carboxylic acid group on the ⁇ -chain link of the basic prostaglandin structure is replaced with electrochemically neutral substituents.
- An example of a hypotensive lipid is that in which the carboxylic acid group is replaced with a C,_ 6 alkoxy group such as OCH 3 (PGF 2a 1- OCH 3 ), or a hydroxy group (PGF 2a 1-OH).
